Abstract

An efficient algorithm is presented for diagnosing faulty sensors by use of x² testing and linear relationships among measurable variables in steady states of continuous processes. A method is also developed for the design of a diagnosis systems utilizing this algorithm. The efficiency of the presented algorithm and the accuracy of the suggested design method are demonstrated by numerical experiments. This method is useful to diagnose baised flow meters by integrated flowrates.
